BACKGROUND OF THE INVENTION

The instant invention relates to alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition containing from about 85 up to about 90% by weight of a compound defined according to the structure: ##STR3## and from about 10 up to about 15% by weight of a compound defined according to the structure: ##STR4## wherein R₁ is hydrogen or methyl and R₂ is hydrogen or acetyl with the proviso that when R₁ is methyl, R₂ is hydrogen and uses of same in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.

Inexpensive chemical compounds which can provide rose, camphoraceous, fruity, woody, green, patchouli, earthy and minty aromas with rose, apple, amber and animalic topnotes and green and woody undertones are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfume compositions as well as perfumed articles are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

There is, accordingly, a continuous effort to find synthetic materials which will replace, enhance or augment the fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree or they contribute undesirable or unwanted odor to the composition.

Cycloalkylalkanols are well known in the prior art and their utilities are known in perfumery.

Belgian Patent 852918 and corresponding Italian Patent No. 1,058,547 disclose the cyclization of dehydrolinalool using polyphosphoric acid to produce 3,3-dimethyl-1-acetyl-1-cyclohexene according to the reaction: ##STR5## wherein, in the structures: ##STR6## these structures are representative of mixtures wherein, in the mixtures one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond. The said Belgian and Italian Patents indicate that the compounds defined according to the structure: ##STR7## are useful in perfumery. Also, U.S. Pat. No. 4,147,672 issued on Apr. 3, 1979; U.S. Pat. No. 4,264,467 issued on Apr. 28, 1981 and U.S. Pat. No. 4.289,659 issued on Sep. 15, 1981 disclose the preparation of the compounds having the structures: ##STR8##

U.S. Pat. No. 3,847,975 issued on Nov. 12, 1974 discloses the use of the compound having the structure: ##STR9## as a perfumant.

Nothing in the prior art discloses the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition containing a high proportion of compounds defined according to the structure: ##STR10## (e.g., 85-90%) and a significantly low proportion of compounds having the structure: ##STR11## (e.g., 10-15%) wherein R₁ is hydrogen or methyl and R₂ is hydrogen or acetyl with the proviso that when R₁ is methyl, R₂ is hydrogen.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIGS. 8 and 9, the apparatus used in producing polymeric fragrances containing at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention comprises a device for forming scented polyolefin (for example) pellets, which comprises a vat or container 212 into which a mixture of polyolefin such as polyethylene and an aromatic substance or scented material is placed (in this case at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention).

The container is closed by an air-tight lid 228 and the air-tight lid 228 is clamped to the container 212 by bolts 265.

A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotated in a suitable manner.

Container 212 having heating coils 212A which are supplied with electric current through cable 224 from a rheostat or control 216 is operated to maintain a temperature inside the container 212 such that polyethylene or other thermoplastic polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ a colorless, odorless polymer (e.g., polyethylene) with viscosity ranging between 180 and 220 saybolt seconds and having a melting point in the range of 220°-280° F. The heater 212A is operated to maintain the upper portion of the container 212 within a temperature range of from 250°-350° F. The bottom portion of the container is heated by means of heating coils 212A heated through control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container within a temperature range of from 250° 350° F.

Thus, polymer (e.g., polyethylene) is added to container 212 and is heated from 10-12 hours whereafter a scented aroma imparting material (at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) is added quickly to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed.

Generally, about 5-30% by weight of the scented material (containing at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) are added to the polyolefin.

After the scent imparting material (e.g., a composition containing at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes, and maintained within the temperature range as indicated, supra, by means of heating coils 212A.

The controls 216 and 220 are connected, respectively, through cables 214 and 222, respectively, to heating coils 212A. The said controls 216 and 220 are also connected through cables 224 and 226, respectively, to a suitable power supply of electric current for supplying the electric power to the heating coils 212A for heating purposes.

Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 218/232 having a multiplicity of orifices 234, adjacent to the lower side thereof. The outer end of the conduit 218/232 is closed so that the liquid polymer (e.g., polyolefin) and aroma imparting material (e.g., at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) will continuously drop through orifices 234 downwardly from conduit 232. During this time the temperature of the polymer (e.g., polyolefin) and scent imparting material (e.g., a mixture containing at least one of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) is accurately controlled so that a temperature in the range of from about 210°-275° F. will exist in the conduit 218/232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer (e.g., polyethylene) and scenting material (e.g., one or more of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention) mixture through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.

When the droplets 236 fall onto the conveyor 238 they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 245 and utilized in a process as illustrated, infra.

A feature of this aspect of the process of my invention is the provision for moistening the conveyor belt 238 to insure rapid formation of the solid polymeric (e.g., polyolefin) scented pellets 244 without sticking to the belt. The belt 238 is advantageously fabricated of a material which will not normally stick to a melted plastic but a moistening means 248 insures a sufficiently cold temperature of the belt surface for an adequate formation of the pellets 244. The adequate moistening means comprises a container 250 which is continuously fed with water 254 to maintain a level for moistening a sponge element 256 which bears against the exterior of the belt 238.

THE INVENTION

The present invention provides alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition containing compounds having the structures: ##STR34## wherein the compounds having the structure: ##STR35## are in an amount in the compositions of from 85 to 90% and wherein the compounds having the structure: ##STR36## are in the amount of from 10-15% in the compositions; and further, wherein R₁ is hydrogen or methyl and R₂ is hydrogen or acetyl with the proviso that when R₁ is methyl R₂ is hydrogen; as well as organoleptic uses of said compositions.

The compositions of matter of my invention produced according to the process of my invention are capable of augmenting, enhancing or providing rose, camphoraceous, fruity, woody, green, patchouli, earthy and minty aromas, with rose, apple, amber and animalic topnotes and with green and woody undertones to perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener articles, drier-added fabric softener articles, fabric softener compositions, cosmetic powders, hair preparations, perfumed polymers, room deodorants and the like).

The alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention are prepared by means of first reacting dehydrolinalool, a mixture of compounds having the structures: ##STR37## with a dehydrating agent such as phosphoric acid or polyphosphoric acid at a temperature in the range of from about 50° C. up to about 170° C. according to the reaction: ##STR38## wherein the compounds having the structures: ##STR39## are indicative of mixtures of compounds wherein in the mixtures one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represent carbon-carbon single bonds.

The resulting compounds defined according to the structure: ##STR40## wherein are in fact in admixture and which are in fact compounds having the structures: ##STR41## wherein the ratio of compound having the structure: ##STR42## to the compound having the structure: ##STR43## is from about 85:15 up to about 90:10.

The resulting mixture of compounds having the structures: ##STR44## is then:

(i) reduced with a reducing agent according to the reaction: ##STR45## wherein Z is a reducing agent such as: ##STR46## or

(ii) reacted with a compound having the structure:

    CH.sub.3 Q

according to the reaction: ##STR47## wherein Q is either Li or MgX wherein X is chloro or bromo to form the mixture of compounds having the structures: ##STR48## which is then hydrolyzed in acid to form the mixture of compounds having the structures: ##STR49## with the ratio of compound having the structure: ##STR50## to the compound having the structure: ##STR51## being from 85:15 up to 90:10.

The mixture of compounds having the structures: ##STR52## may, if desired, be further reacted with an acylating agent such as acetic anhydride according to the reaction: ##STR53## whereby the compounds having the structures: ##STR54## are formed with the ratio of compound having the structure: ##STR55## to the compound having the structure: ##STR56## being from 85:15 up to 90:10.

The attempt to react the mixture of compounds having the structures: ##STR57## with acetic anhydride did not result in the corresponding acetate drivative.

The reaction, to wit: ##STR58## is carried out according to the conditions taught by Belgian Patent No. 852,918 published on Jul. 18, 1977 or Italian Patent 1,058,547 published on May 10, 1982 at a temperature in the range of from about 50° C. up to about 170° C. in the presence of phosphoric acid or polyphosphoric acid and, preferably, in the presence of a solvent such as toluene. Indeed, the product which is a mixture of compounds having the structures: ##STR59## is marketed by Givaudan-Roure of Wayne, N.J. under the trademark "ARTEMONE®".

The subsequent reduction according to the reaction: ##STR60## where Z is a reducing agent which is preferably one of the materials: ##STR61## is carried out at a temperature of from about 50° up to about 70° C. in the presence of an inert aqueous solvent such as aqueous isopropyl alcohol.

The subsequent reaction (if desired), to wit: ##STR62## is carried out in the presence of an esterification catalyst, preferably paratoluene sulfonic acid; preferably at a temperature in the range of from about 60° C. up about to 80° C.

Examples of the reduction reaction are set forth as follows: ##STR63## (wherein M represents sodium or potassium) and ##STR64##

The reaction: ##STR65## is carried out at temperatures in the range of from about -5° C. up to about+5° C. in the presence of an inert solvent such as diethyl ether or tetrahydrofuran. The mixture of salts having the structures: ##STR66## is then subjected to hydrolysis with acid (e.g., aqueous hydrochloric acid or aqueous sulfuric acid) according to the reaction: ##STR67## The hydrolysis reaction is carried out at a pH of from about 2 up to about 5. Other acids which may be used are, for example, acetic acid. Examples of the methylation reaction are as follows: ##STR68##

Examples of the hydrolysis reaction are as follows: ##STR69## wherein X represents chloro or bromo and Q represents Li or MgX.

In all cases the resulting reaction product is distilled via fractional distillation and the final product is then utilized as indicated, infra, for augmenting, enhancing or imparting fragrance nuances to perfume compositions, colognes and perfumed articles.

One or more of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition prepared in accordance with the processes of my invention and one or more auxiliary perfume ingredients including, for example, alcohols (other than the alcohols of my invention), aldehydes, ketones (other than the ketones of my invention), terpenic hydrocarbons, nitriles, esters (other than the esters of my invention), lactones, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the woody, minty, herbaceous, spicy and tagette fragrances. Such compositions usually contain:

(a) the main note or the "bouquet" or foundation stone of the composition;

(b) modifers which round-off and accompany the main note;

(c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and

(d) topnotes which are usually low boiling, fresh smelling materials.

In perfume compositions, it is the individual components which contribute their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition prepared in accordance with the processes of my invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, cationic, nonionic or zwitterionic detergents, soaps, fabric softener compositions, fabric softener articles and perfumed polymers) and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition prepared in accordance with the processes of my invention or even less (e.g., 0.005%) can be used to impart, augment or enhance rose, camphoraceous, fruity, woody, green, patchouli, earthy and minty aromas, with rose, apple, amber and animalic topnotes and green and woody undertones to soaps, cosmetics, anionic, cationic, nonionic or Zwitterionic detergents, fabric softener articles, microporous polymers, particularly acrylic resins, polyethylenes and other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders, microporous "perfumed" slow release polymers and the like.

When used as (an) olfactory component(s) in perfumed articles, as little as 0.005% of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition prepared in accordance with the processes of my invention will suffice to impart, augment or enhance rose, camphoraceous, fruity, woody, green, patchouli, earthy and minty aromas, with rose, apple, amber and animalic topnotes and green and woody undertones. Generally, no more than 6% of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention based on the ultimate end product is required in the perfumed article. Accordingly, the range of use of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention in perfumed articles, per se, is from about 0.005% up to about 6% by weight of the perfumed article.

In addition, the perfume composition or fragrance composition of my invention can contain a vehicle or carrier for the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition prepared in accordance with the processes of my invention. The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethyl alcohol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g., gum arabic, guar gum or xanthan gum or a combination thereof) or components for encapsulating the composition (such as by coacervation) using prepolymers such as urea-formaldehyde prepolymers which are able to form a urea-formaldehyde polymer capsule around a liquid perfume center.

It will thus be apparent that the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention can be utilized to alter, modify or enhance sensory properties particularly organoleptic properties such as fragrances of a wide variety of consumable materials.

The following Examples I, II and III set forth means for preparing the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention. The examples including and following Example IV, infra, set forth illustrations of organoleptic utilities of the alpha, 3,3-trimethyl-1-cyclohexen-1-methanol derivative-containing composition of my invention.

All parts and percentages given herein are by weight unless otherwise specified.
